Ergonomic keyboard systems and methods

Abstract

The present invention provides ergonomic keyboards and methods of using such keyboards. In particular, the present invention provides split keyboards for use on non-traditional surfaces such as body parts and provides keyboard components having one or more additional non-keyboard functionalities (e.g., point-and-click capabilities).

Description

[0001] The present invention claims priority to U.S. Provisional Patent Application Ser. Nos. 60 / 681,813, filed May 17, 2005, 60 / 710,745, filed Aug. 24, 2005, and 60 / 748,991, filed Dec. 9, 2005, each of which is herein incorporated by references in their entireties.FIELD OF THE INVENTION [0002] The present invention provides ergonomic keyboards and methods of using such keyboards. In particular, the present invention provides split keyboards for use on non-traditional surfaces such as body parts and provides keyboard components having one or more additional non-keyboard functionalities (e.g., point-and-click capabilities). BACKGROUND OF THE INVENTION [0003] For many people, using computers is physically uncomfortable. Many people suffer back, neck, elbow, and wrist pain and injuries due to using a keyboard and mouse. Most computer keyboards force users to keep their hands, wrists, arms, shoulders, etc. in the same locked position, often causing users fatigue and injury. Keyboard tra...

Benefits of technology

[0023] Instead of forcing the person to adapt their posture to the keyboard, the present invention adapts the keyboard to the person's posture and arm position allowing the user to sit more comfortably and in many more positions. The present invention allows the computer user to achieve an ergonomically correct typing position in many more environments than standard keyboards and mouse. In some preferred embodiments, the present invention combines the keyboard and mouse together, eliminating the need to have to reach for the mouse and helping to eliminate repetitive motion or other afflictions relating to its use. The present invention also allows its user to keep the desktop clear without the need of a special desk or computer tray. In some preferred embodiments, the present invention provides redundancy of functions (e.g., mouse functions, scrolling, clicking, etc.) to allow the user a diverse set of hand positions that can be altered over time to reduce repetitive stress.

[0083] In some embodiments the device has one or more auxiliary ports (e.g., USB, PS / 2, IEEE-1394, serial, parallel, etc.) allowing the user to easily switch components and easily connect auxiliary devices (e.g., flash drives, MP3 players, cameras, etc.). In some embodiments, one or more auxiliary ports use one or more standard interface protocols such as USB, PS / 2, IEEE-1394, serial, parallel, or wireless connections (e.g., a wireless repeater or amplifier port). In other embodiments, the auxiliary ports use any suitable wired or wireless connection protocol.

Problems solved by technology

These systems and methods solve many problems associated with the more ergonomically limited systems and methods currently in use.

A very common problem related to the use of computers is stress and strain arising from the need of the typist to adopt a relatively stationary, often erect and rigid posture when touch typing.

Different types of keyboards and pointing devices have been designed to minimize these problems, but none of them address the fundamental issues relating to a person having to sit in one position doing repetitive movements for long periods of time.
